Leica 10x42 Ultravid HD-PLUS binoculars feature the new Schott HT glass and revamped coatings. Ultravid HD-PLUS binoculars are made with Leica’s proprietary AquaDura water-shedding coating, the P40 phase-corrective coatings on the prisms and the HighLux System to ensure the brightest, high-contrast images while minimizing the impact of stray light. Light transmission and resolution of the Ultravid HD-PLUS binoculars are further enhanced by the full HDC multi-coating on all the lens elements in each barrel. Black rubber armoring covers the durable magnesium frame of the 10x42 Ultravid HD PLUS binoculars which weigh 26.8 ounces. Fully sealed and nitrogen filled, the Ultravid 10x42 binoculars are waterproof to a depth of 16.5 feet and internally fog-proof as well.

Leica’s got the SCHOTT HT

Outstanding Optical Performance

Reliable and Durable Mechanics

Now featuring the SCHOTT HT (high- transmission) glass lenses with 92+% light transmission found in top end Leica binoculars for amazing image brightness and clarity.

Leica’s full HDC multi-coating on all of the lens elements offer further light transmission for amazing image clarity, brightness, and contrast in low-light settings.

P40 Phase-Corrective coatings on the prisms and the HLS anti-reflective (dielectric system) to ensure the absolute minimum impact of stray light and chromatic aberration for an absolutely perfect, clear image.

AquaDura lens coatings cause water to ball up and roll off the optical systems for clear vision in tough weather while also protecting the lenses from scratches and abrasions.

Comparable Field of View with 336 ft. @ 1000 yds.

Nitrogen filled to prevent fogging

100% Waterproof

Doublewide Focus Knob rivals competitors with 1.3 turns to switch from close focus to maximum observation distance. The large center focusing mechanism removes strain on the finger and improves balance for the fastest focus.

Intuitively placed Diopter Ring in the front center for easy access and quick adjustment of individual compensation between left and right eyes as well as a visual scale setting on the front face of the Diopter so you never lose focus.

Shock Absorbent armoring made from high performance Polyamide for robustness and low weight protects the binoculars against damage.

Schott HT Glass lenses – is an innovative optical design standing for ‘High Transmission’ lenses by SCHOTT, a sister company of Zeiss and represents light transmission capability that were previously unheard of - reaching up to 95% of light gathering power. It was developed to ensure that critical details can still be seen even in the deepest twilight.
Leica has adopted this technology for maximum image sharpness and color correction in conjunction with their advanced P40 Phase-Corrective and the HLS anti-reflective (dielectric system) coatings on the prism to ensure the absolute minimum impact of stray light and chromatic aberration for an absolutely perfect, clear image.

Multi-Layer Lens Coatings: This basically means that the lenses have received multiple layers of anti-reflective coatings on all air-to-glass surfaces which increase light transmission to produce a brighter image and therefore better low light performance. Anti-reflective coatings can make a really big difference on the brightness of the image produced. It is not unusual to look through binoculars with smaller objective lenses, but with higher quality anti-reflection coatings and seen them outperform binoculars with much larger objective lenses, but with fewer or no coatings. The diagram above shows how these coatings improve the transmission of light.

Phase Correction: Phase correction is a set of coatings on the prism glass of roof prism binoculars that keeps light in correct color phases. These coatings are only needed on roof prism binoculars to enhance resolution, contrast, and color fidelity.
The top half of this image shows the benefits of phase correction.

Leica AquaDura Lens Coating:
That is the water repelling characteristic of surfaces to simply let water drops pearl off and to repel dirt. Leica’s AquaDura coating does just that and in conjunction with the HDC coating, the lens surfaces become extremely resistant to abrasion and other environmental influences and also making cleaning and care especially easy.

Focus Mechanisms Re-Defined:
Leica’s Ultravid HD series focus mechanisms have been further refined for an even smoother, faster operation. Typical focus mechanisms use grease or lubricant where in higher temperatures, they move too freely or even escape the mechanism causing damage, and at low temperatures they can feel sticky making for ‘jumpy’ difficult focusing.
Leica’s optimized, gliding focus disks use paired materials that work without lubricants so even in extreme temperatures, they remain fully functional and maintain a consistent smoothness of touch so that your Ultravids can be used in any climate and maintain their high-performance.
